A rectangular coil of length 0.12 m and width 0.1 m having 50 turns of wire is suspended vertically in a uniformmagnetic field of strength 0.2 Weber/m2. The coil carries a current of 2 A. If the plane of the coil is inclinedat an angle of 30^° with the direction of the field, the torque required to keep the coil in stable equilibrium willbe [(1)0.12 Nm (2)0.15 Nm (3)0.20 Nm (4)0.24 Nm |
